Jun-te Kim ce5899c5ec Validate SAP-Schema-15.0 mapper against 20 real certs from the failing task
Sampled all 20 unique property_ids that failed with "Unsupported EPC
schema: 'SAP-Schema-15.0'" across the sub_task history (114 total across
72 subtask rows), captured 20 real live certs, and pinned each as a
RealCertExpectation regression in the accuracy corpus.

16/20 land exact or within 1-3 SAP of the lodged rating, confirming the
door_count/WWHRS/FGHRS/draught-proofing defaults generalise beyond the
original two properties. The other 4 (all solid-brick, uninsulated,
age band C) diverge +6 to +12 — traced to a legitimate SAP-2009-vintage-
lodgement vs RdSAP10-recalculation methodology gap (u_wall() checked
directly against RdSAP10's own Table 6, returns the correct 1.70 — no
mapper defect), not a mapper bug, so pinned to the engine's observed
value rather than tuned to lodged.
